Single substrate single product reversible enzymatic reaction with parameters for phospho-gluco isomerase in erythrocytes (Ref 1)


  Single substrate single product reversible enzymatic reaction with 
  parameters for phospho-gluco isomerase in erythrocytes (Ref 1).
  Follows the Haldane constraint that the reaction is reversible
  and there is an equilibrium ratio of concentrations given by
  Kappa = [P]/[S] at equil = k1*k2/(k_1*k_2),  Eq 10-29 in 
  Bassingthwaighte's Chapter 10 on Metabolism.(Ref 2)


The equations for this model may be viewed by running the JSim model applet and clicking on the Source tab at the bottom left of JSim's Run Time graphical user interface. The equations are written in JSim's Mathematical Modeling Language (MML). See the Introduction to MML and the MML Reference Manual. Additional documentation for MML can be found by using the search option at the Physiome home page.
